Application filed September 6, 1902. Serial No. 122,434.

Be it known that I, JAMES GARDNER SAN- DERSON, a citizen of the UnitedStates, residing at Scranton, in thecounty of Lackawanna,

State of Pennsylvania, have invented certain" new and usefulImprovements in Street-Cleaners, of which the following is aspecification.

The object of this invention is to produce an improved street-sweepingmachine of the motor-vehicle type in which the parts will be compactlarranged and so constructed that the vehic e may be propelled while thesweepmg and collectin mechanism is inactive, or the sweepin ancollecting mechanism may be em loye while the vehicle is stationary, orbot mechanisms may be operated simultaneousl 'A further object is toprovide an improved construction for conveying the sweepings fromthe'brush to a bag or other receptacle. With these and minor objects inview the invention consists of the parts and combinations of partshereinafter described, and pointed out in the appended claims.

. In the drawings formingapart of this specification, Figure 1 is a topplan view of the machine with parts broken away to disclose the interiorconstruction. Fi 2 is a vertical section on the line 2 2, Fig. 1; andFig. 3 is an end view of the bag-filler. Fi 4 is a vertical section ofthe chain-casing, s owing the position of the parts therein.

e numerals indicate like parts throu h all the figures of the drawingsand in t e specification.

Referrin more articularly to the drawings, l in icates the frame of thevehicle, which is mounted upon two front wheels 2, secured to the axle3, and the steering-wheel 4, secured to the steering-fork 5, journaledin the .rear of the frame and controlled by a steering-lever 6. Theframe 1 is divided into two compartments, one in the rear, as shown at7, WhlCll the-operator occupies to control the machine and whichreceives the sweepings, and one in front, as shown at 8, in which ismounted the operatin mechanism. I

The vehicle is prope led by any kind of motive power; but it ispreferable to mount an electric motor 9 in the compartment 8 and connectthe same with the axle 3 by means of reducingearing 10. The current forthe motor is obtained through wires 1 1 from cells 12, located in thelower part of the rear compartment 7, a switch 13 inthe compartment 7controlling the current. a K

The sweeping and collecting mechanism receive their motion from a shaft13 journaled in the front compartment 8. This shaft'lis rotated by anymotive power, but referably by a motor 14, connected therewit by gearingand chain 15, and this motor receives its current from the cells 12,before mentioned,..

through wires 16 and is controlled by switch 17 ,-mounted in the rearcompartment 7.

A rotary brush 118 is mounted in'advance of the vehicle and is journaledin the forward part of a collectin -casing 19. In the rear of the brushand in t e casing is mounted for receiving the sweepings from thebr'usha receiving-shelf 20, the under side of which is provided withperpendicular sheet-scra ers 21, which remove any dirt not remove bybrush. The receiving-shelf 20 is inclined at its forward portion, asshown at 22, and has a channel 23 at its rear. In this channel ismounted a conveyer 24, preferably a screw.

To operate the brush l8 and conveyer 24 and at the same time to permitthe brush 18 and scrapers 21 to rise and fall so that an unevenness inthe surface to be cleaned wi 1 not interfere with the operation of themachine, the receiving-casing 19 is swung from.

the shaft 13 by means of a chain-casmg 25 and a conveyer-casing 26. Thechain-casing 25 is journaled on the shaft 13 and the shaft of the screwconveyer 24 and has mounted within it a chain 27, which communicatesmotion from thegear 28 on the shaft 13 to the gear 29 on the shaft ofthe screw conveyer 24, which shaft in turn communicates rotation throughthe Theconveyer-casing 26 is j ournaled at its center to the shaft 13and at its lower end to a shaft 33 on the collecting-casing 19 andadjacent to the screw conve er 24. The conveyer-casing being j ourna edto the frame 1 and to the collecting-casing 19, the casing is permittedto rise and fall relatively to the ame 1, and the conveyer is always ina position to convey the sweepings from the casing 19 to the frame 1, itpartaking of the movement of the casing 19.

The up er end of the conveyer-casing 26 carries a ag-filling device 34.Within the conveyer-casing is mounted an endless conveyer 35 of anyknown variety, which passes gear 30, chain 31, and 2 gear 32 to thebrush 18.

around a pinion 36 on the shaft 33 of the collecting-casing 19 and apinion 36 on a shaft 37 in the u per part of the conveyer-casing. Theends of the shaft 37 extend beyond the sides of the casing 26 and arerovided, respectively, with pinions 38 an 39. Pinion 38 is connected,through the medium of chain 40, with a pinion 41 on the shaft v13 to communicate motion from said shaft 13 to the conveyer 35.

The ba filling device 34 consists of a horirontal to e 42 at rightangles to the cnveyercasing 26, having a flared downwardly- I end t3,around which is secured a bag by an elastic band 43. This band permits,should the operator be inattentive, the bag when full to be forced offof the flared end 43, and thereby prevents the mechanism which conveysthe sw-ee ings to said bag being broken, which W0 (1 be theresult if thebag were not removed; Within the tube 43 is a "screw conveyer 44, whichreceives motion from the pinion 39 on the shaft 37 of theconveyer-casing. I

When it is desired that no sweeping shall be done by the machine, the oerator lifts the collecting-casing by means 0 a cable 45, secured tosaidcollecting-casing, passing over pulleys 46 and 17, depending into therear compartment and having a stirrup 48, in which the operator placeshis foot.

A handbrake 49 on the axle 8 is provided.

and is operated by a lever 50, which connects with the band by a rod 51.

The operation of the machine is as follows: The motors bein started,motion is communicated to the an e 3, whereby the machine is propelled,and-to the shaft 13, which rotates the brush, through the medium ofchains 27 and 31, in the direction of the travel of the machine, andthereby assists in its propulsion. The dirt is swept by the brush 18into the channel 23, which it is conveyed by the screw 24: to theconveyer-casing 26, where it siaeoo struction may be made withoutdeparting from the spirit of my invention.

Having thus described the invention, the following is what i claim asnew therein:

1. The combination with the frame, a shaft carried thereby, and meansfor rotating the shaft, of a collector-casing carrying a brush,

two casings journaled on the shaft and to the collector-casing,mechanism for operating the brush from the shaft mounted in one of thecasings, and a conveyor also operated by the shaft mounted in the othercasing.

2. The combination with the frame, carrying a motor, and acollector-casing carrying a brush, of two casings connecting thecollector-casingwith the frame, brush-operating mechanism mounted in oneof the easings, and a conveyor mounted in the other casing.

3. in a street-sweeper, the combination with the collector mounted inthe front ofthe machine-frame and comprising a casing, a rotary brushjournaled in the casing, a shelf mounted in the rear of the brush and asingle screw conveyer carrying the material received on the shelf, toone side of the collector; of a conveyor extending from the side of thecollector, a motor carried by the machine, connections between themotor, the conveyer and the brush whereby the two latter are operated bythe former, and inde-.

pendent means for propelling the machine.

brush mounted in advance of the frame and movable up and down relativelythereto, a
